Quarantine Technology And Risk Analysis Of Oriental Fruit Fly (Bactrocera Dorsalis)

With the method of system investigation, and indoors feed experiment combine together, the morphologic identification and mole-biological identification technology, biological characteristic, ecological characteristic of oriental fruit fly (Bactrocera dorsalis) were studied。 The survival characteristic and introduction risk of oriental fruit fly were system analysised.1. The identification technology of oriental fruit flyMorphologic characteristic was mostly gist for species identification. The most morphologic identification characteristic of oriental fruit fly was described in this paper, and the morphologic identification characteristic of analogous species fly were compared, The adult identification key of constant quarantine fly species of Bactrocera were authorized, to satisfy the usage of oriental fruit fly celerity and authentic identification. According to the observed result of entrapping responses, the especially responses to the attractant Me of oriental fruit fly could was used to assistant identify. With the technology of Polymerase Chain Reaction (PCR) and denaturing gradient gel electrophoresis (DGGE), the oriental fruit fly and it's analogous species could be quickly identify, especially in the identification of flyblow and larva which were difficult to identify by the morphologic characteristic, the foundation of forepart identification of fruit flies was established.2. The biology speciality of oriental fruit flyBy system investigation and indoors feed experiment observe , The emergence, feeding, copulation, oviposit and longevity of oriental fruit fly were particularity described. The host and their suffer injury degree in Fujian province were proved up. The threshold developmental temperature (C) and the total effective temperature (K) were determined . 6 generations per year in Fuzhou city, population dynamic and it's influence factors of oriental fruit fly were proved up.
